PROCESS OF MANUFAGTURING SOLUBLE CGMPOUNDS F MERCURIC SALTS WITH HEXAMETHYLENE-TETRAMIN.

of philosophy,

instance mercuric chlorid. The hexamethylene-tetram-in-mercuric-double salts are produced by mixing aqueous or alcoholic solu-' tions of the components, viz. hexamethylenetetramin and mercuric chlorid. In aqueous solution a precipitate will result of the composition of one molecule of hexamethylenetetramin to two molecules of mercuric-chlorid; in alcoholic solution, the composition of the precipitate will be one molecule of hexamethylene tetramin to one molecule liner-- curic-chlorid. These do'uble salts of hexamethylene-tetramin and mercuric, chlorid are very sparingly soluble in water and the usual organic solvents.

I have now discovered that the double salts of hexameth'ylerietetramin and. mercuric chlorid, mentioned above, which are neither soluble. in a solution of an albuminoid nor in a solution of soap, each for itself, becomes soluble when treated with a mixture of the albuminoid-and soap solution. In' a solution, obtained in this way, the mercury is bound up in an organic state, that is to.

say, it is no longer precipitable by the usual reagents such as sulfureted hydrogen, ammonium sulfid, caustic potash, etc. These solutions of hexamethylene tetramin mercuric chlorid in albumin and soa solution behave on the other hand quite ifierently from pure mercuric chlorid solutions. While the latter will precipitate albuminous matter from its SOllltlOIl and corrode, as is well known, the skin, the former neither precipitate a solution of albuminous matter nor do they afi'ect the skin. They are thereinfectants. Y

My invention'consists in the application of this discovery.

en, for instance, dry hexamethylenetetramin-mercuric chlorid is mixed with an equal weight of 'an albuminoid, soluble in low particularly suitable to be used as dis- Specification of Letters Patent.'

Water, such as-albumose, peptone, alkali-albuminate, casein alkali or the like, and the mixture is dissolved in a soap solution, the mercury of the solution is in an organic form and no longer to be precipitated by the usual reagents for precipitation of mercury.

Instead of mixing hexamethylene-tetramin-mercuric-chlorid and albuminous matter, mentioned above, in a dry state and dissolving the mixture in a soap solution, the process may be also performed by incorporating hexamethylene tetramin mercuric chlorid in a mixture of soap and albuminous matter, or the hexamethylene-tetramin-mercuric chlorid can be mixed with dry albu minous matter, soluble in water, and this mixture kneaded with solid soap, as in using the soap, thus produced, solution will ensue.'

Such solutions contaming the mercury bound 'up in an organic form are found to be less corrosive than an equivalent solution of pure mercuric chlorid, although of equal disinfecting power; they are therefore particularly suitable for practical use.

The following exam les will show, how the process is to be per ormed:

grams of dry hexamethylene tetramin mercuric chlorid are mixed with an equal weight of albumose and the mixture is introduced into 97.5 coin. of a soap solution of 5 per cent. strength made by dissolving 50 grams of medicinal soap in one liter of water; the mixture is stirred and gently heated until solution will ensue. The solution thus produced, corresponds with one of mercuric chlorid of about 1 per cent. strength and may be diluted with water as desired.

Example II: 5 grams of medicinal soap and 1.25 grams of albumose are dissolved in about 95 com. of luke-warm water and to the will result a solution which contains mercuric double salt, albulnose and soap in the, same proportions as the ingredients are found in the solution of Example H.

Instead of albumose any other albuminous matter, soluble in water, such as peptone, alkali-albuminate or casein alkali may be used.

The proportions of mercuric double salt, albuminous matter and soap may be varied Within certain limits, Without essentially changing the character of the solution in respect of the organic combination or the mercury.

What I claini and desire to secure by Letters Patent of the United States is:

1. The process of producing'solutions of hexamethylene tetraniin mercuric chlorid which contains the mercury in an organic form not capable of being precipitated by the usual precipitants, by dissolving the meI'-,

' matter,

of a product consistin curic double salt aforesaid in a solution containing a mixture of soap and albuininous which is soluble in Water. 2. A disinfecting composition consisting .of hexaniethylenetetramin-mercuric chlorid, albuminoids soluble in Water, and soap.

3. A disinfecting composition consisting of an aqueous solution containing hexamethylene-tetramin mercuric chlorid, albuminoids soluble in water, and soap.

In witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses;
